ing the interior arrangement of thehousin'g I r 12 it will be noted that a plate 13 is secured by means of its laterally directed ends 13 to the frontwall-of the housing in any pre-' ferrecl manner, the plate-13 being spaced therefrom as clearly shown in-Figure 2 for a purpose that will presently appear'.- Secured to the outer surfaceiof this plate 18 is an angle plate 14, its fastening means in jecting' upwardly therethrouglr from the hel-clcasin of a:smallielectriciiihctoi jfl'h" I V which sfirinly' secured to; the under surface- I of the laterally"prdj eetingfportion of the-i angle plate bymean's of nuts; screwed the threaded-ends ofthe'stutl's 16-1 its armature shaft with a small-pinion18 for1 meshing engagement with-a gear 19 jouh he motor 17 is pro'vicleclatthe enti :1

In operationlt Will be evident that when the motor 17 'is' started a rotary movement the form of machine screws 14:? being shown will be imparted 'tOthe cam 26 throughf the I medium of gears-19, 21, and 22, this operation resulting in the rocking of the pitman in a vertical direction as shown in Figure 4. Throughthe medium of pinion 30 the arm 32 will be reciprocated, its resiliency tending to maintain the wiping element 34 pressed against the outsideof the glass at alltimes for removing accumulations therew some moving part of' the vehicle.

from. By using the pivotal-connection 35,

. ,thisc'onnect-io-n being at the central part of the Wiping element it will be clear that the entire Wiping surface thereof 'will at all times be pressed againstthe glass.

In Figure 6 I have illustrated a slightly modified form of the invention embodying a driving element which may be driven from In this instance Ihave shown the plate 13. as usual but the gear 22 has been 'replaced by the beveled gear 22 and the motor 17 with its driving connection'has been replaced by the collar 37 which is fastened to the plate 13 bymeans'of screws 38. hiscollar 37 forms a" bearing for a short shaft 36 carrying a bevel gear 21 in mesh with gear 22.

5 driving connection may. be had. between a '7 moving part ofthe vehicle and the shaft 36 by means of a flexible driving means 39 car ried within a flexible shaft 40. The cam 26 is carried upon the shaft 24 as usual and the rest of the mechanism operates as previously 7 d'escribed- From the foregoing description, read in connection with the accompanying drawings, 7

that the driving means may be'removed.

without interferingwith the other elements or necessitating dismantling of the device. Likewise the driving 'means of Fig. 5 can be substituted for" that of Figs. 2 and 3 with equal facility.

The direct alinement of the pitman '27 with the cam 26 and the gear .30 with which elements it is engaged, together with the "adjacent and opposite journalling of all, in-

sures extreme rigidity, a minimum of frictionand Wearfwith accompanying long life The spaced plates of the bearing surfaces and silent operation.

'The illustrated embodiment of the invention isespecially, adapted for rapid production since the plates 18 and 25 together with the pitman 27 may beproduced from flat steel stock by use of the punch press after; which they'may be heat treated.

The shaft 24 with the integral eccentric 26 constitutes a very simple screw-machine problem. The other. elements may likewise be made very readily from eitherstampings'or castings.

Fig. 2 illustrates that the plates 18 and I 25 cooperate with the spindle shaft gearSO and the cam 26 so as to preventlateral displacement of the same together with their shafts. I

While I have described the preferred em bodiment of my invention as required by the patent statutes, yet it will be under stood that I do not propose to be'limited strictly thereto since various changes'and modifications thereof will immediately sug- 'gest themselves to those skilled in the art within the spirit of my invention, the scope of which. is defined bythe following claim." described my invention, 7

Having thus what I claim as new and desire to secure by Letters Patent is. p

A driving mechanism for oscillatory windshield wipers includinga pair of spaced. and rigidly connected plates constituting a support through which the wiperarm spin- 7 dle-is journ'all-ed, a gear keyed upon said spindle shaft, the aforementioned plates being so spaced as to cooperateiwith the hub portion of said gear to prevent lateral movement of said shaft; anoscillatory arm journalled between said spaced plates, rack teeth, 7

formed at one end of said arm cooperable with said. wiper arm spindle gear for oscillating. said wiper arm; a driven shaft" journalled in saidspaced plates and project ing beyond the outer face of one of the same,

driving means associated with the projecting end of said drlven'shaft; a radial proection carried upon said driven shaft inter IOU mediate'said plates, said radial projection.

having an operative connection. with said oscillatory arm whereby an oscillatory motion is imparted thereto when said shaft is in 7 motion; and the spaced plates cooperating with said radial projection to prevent lateral movement of said driven shaft.

In testimony whereof I aflix my signature. MARTEN REYNHOUT.
